-`kableExtra` also provides a few inline plotting tools. Right now, there are `spec_hist` and `spec_boxplot`. One key feature is that by default, the limits of every subplots are fixed so you can compare across rows. Note that in html, you can also use package `sparkline` to create some jquery based interactive sparklines. Check out the end of this guide for details.
